I my advice is buy a “N” router (it’ll do everything else too) I liked my Linksys router, I have a net gear router that has been very good (though it does seem people don’t like netgear as much) and I had a Zoom Cable modem/ wireless N router that worked really nice, except for online gaming with my xbox, I’m back to my netgear router and a modem.
Really when I’m looking at reccomendations I read the customer reviews on Best buy and Amazon, looking at the most popular and most reviewed ones first, reading all reviews (won’t take long) So people give high reviews and know nothing really, some know a lot, so you can probably tell the difference.
When You got it narrowed down, if you want to be extra sure, google the model number and “review” Probably find a cnet review or something, from someone you know you can trust.
In all reality it’s probably hard to bad one if you get a name brand and spend a fair amount on it ($40-$100).
